Understanding the Cooling Terms of Industrial Chillers for Data Centres

Kinds of Industrial Chillers

 

Here are some of the air conditioning/cooling terms used in industrial chillers for data centres:

BTU

BTU or British thermal unit is a measurement of heat energy that is typically utilised to calculate the heat loads in data centres. It is the sum of heat energy needed to increase the temperature of 1 pound of water, by 1 degree °F, in an hour.

Ceiling mount

A ceiling mount is a little precision air conditioner suspended from the ceiling. It is usually attached to a heat rejection unit, in an outdoor area, through water lines or a refrigerant.

Chilled water system

A chilled water system is commonly used in medium to large data centres. The cold water is loaded from the chiller to the computer room air handlers. This helps to cool the area.

Chiller

A chiller constantly cools great volumes of water. It utilises the cooling cycle to supply large volumes of cold water that is further dispersed to Computer Room Air Handlers (CRAH) units. CRAH units are responsible for eliminating the heat from the data centres.

Compressor

A compressor is a vital component in the cooling cycle that utilises motorised energy to compress a gaseous cooler. This enables an air cooler to attract heat at a certain level of temperature and dispel it outside at a possibly greater temperature.

Condenser coil

A condenser coil is the method of eliminating heat that is frequently utilised in an air-cooling system. It is responsible for transmitting the heat energy from a cooler to its external surroundings.

Dehumidification

Dehumidification is the method of reducing or eliminating moisture from the air. In a data centre, dehumidification mostly happens when the air filled with moisture runs through the cold evaporator coil.

EER

EER (Energy Efficiency Ratio) is a measurement that calculates the operations of a compressor proportional to its power consumption.

Evaporator coil

An evaporator coil looks the same as a vehicle radiator. It is typically used in places that require heat removal. The cool air that comes from an air conditioner transmits heat energy to the flashing cooler when it goes through the evaporator coil.
